Alloy Analysis

Analyze Any Alloy in Seconds with a Bruker XRF Gun!

Alloy Analysis ExampleModern civilization largely depends on the quality and precision of metal alloys. Bruker Inc. prides itself on making robust handheld X-Ray Fluorescence (XRF) alloy analyzers that scan and analyze the chemical composition of alloys in 2 or a few more seconds, depending on the application. Use the form to the right to contact Bruker Inc. for details pertaining to your specific application, to arrange a free demo, or for a prompt quote.

Bruker elemental is a worldwide market leader in cutting-edge, nondestructive alloy analysis solutions using X-ray fluorescence. A portable Bruker alloy analyzer is a most efficient and effective means to perform multi-element alloy analysis, determining alloyant concentrations in objects of any shape. A Bruker alloy gun is small and eminently portable, making alloy analysis easy to perform in situ or in a lab. Usually, no sample preparation is required. With the pull of a trigger, the S1 TITAN quantifies nearly any element, from Magnesium to Uranium. Whether in the scrap yard or on the manufacturing floor, it quickly and accurately identifies alloy grades and lists the concentrations of the constituent elements and trace elements in a clear on-screen readout.

An alloy is a combination of a metal with one or more metallic or nonmetal chemical elements. Alloys are characterized by the metallic type of structural bonding – the attraction force between the metal atoms and the free-floating valence electrons – which acts as a "superglue" and defines the alloy’s structure. Analysis with an electron microscope shows that the atoms in an alloy mass form a crystalline lattice, arranging themselves regularly much like marbles in a jar. Most atoms are provided by the main metal, with those of alloyants occurring throughout the lattice. When analyzed by an X-Ray Fluorescent spectrometer gun, an alloy is briefly irradiated with high-power X-rays. This “excites” the atoms of the constituent elements, which in turn emit a secondary X-ray radiation, termed “fluorescent.” Each element’s X-ray fluorescent signature is spectrally unique, allowing for identification and quantification by an XRF alloy analyzer. That is, in a nutshell, how a Bruker gun works.

Alloys are widely used for their individual properties, such as hardness or malleability, corrosion resistance, etc. In certain cases, alloys are used in industrial applications when it is necessary to lower the price of material by “diluting” the expensive metal in it, while keeping its desired properties. In science, the alloy constituents are typically measured in (atomic) parts per million (ppm), while in the industrial and commercial context the proportions are usually expressed in percentages by weight of course, nature makes numerous alloys of her own, which are also analyzable by XRF. Most of the approximately 90 naturally occurring chemical elements are metals. Industrially manufactured alloys must conform to declared specifications and standards, which makes the importance of reliable alloy analysis self-explanatory.

The human world is built on alloys. Unalloyed, “pure” metals are often imperfect solutions to our needs: they tend to be too soft or to break or corrode too easily. These shortcomings can be overcome by alloys because they can develop synergistic properties that are different from those of the individual constituents. (Countless alloy variations are theoretically possible, and multiple thousands are on record in industry.)For example, Pure aluminum is light but weak. Pure iron is strong but rusts. However, aluminum becomes hard when alloyed with copper (another soft metal) and aluminum alloys are prized for their high strength-to-weight ratios, while iron serves as the most popular alloy base in the world, giving us the steels, including the stainless steels, alloy steels (including the so-called, low alloy steels), plain carbon steels, as well as cast iron. All these alloys have uses far beyond what their pure bases are capable of. Complex modern alloys can support unique sets of characteristics; some aerospace alloys combine 10+ elements. Obviously, such alloys require very tight quality control, a job well performed with a Bruker alloy analysis gun.

Basically, alloy is an “admixture,” an impure blend of chemical elements, but what distinguishes an alloy from other types of admixtures is that an alloy retains recognizably metallic properties, although not all the elements in an alloy may be metals. Although technically “impure” of their nature, alloys also contain impurities in the strict sense, i.e. undesirable elements. When present in evasive quantities (which can nevertheless adversely affect an alloy’s properties), elemental impurities are commonly termed “trace elements.” For example, S reacts with Fe, yielding a brittle ferrous sulfide (FeSO4) that causes weak spots in the steel. The presence of Ca, Li and Na can compromise the structural integrity of aluminum alloys. Many impurities are readily reducible by metallurgical refining, while others can be pesky and hard to get rid of. Their presence can negatively affect the price of material. Bruker alloy analysis guns play a central role in impurity control. Our systems offer you the highest analytical stability and accuracy. Questions? Message us now!

More Information

Bruker alloy analyzers can perform alloy grade verification for most for the vast majority of standard alloys, based on an extensive internal alloy grade library. Analysis also provides the elemental composition (within its range) of any nonstandard alloys. The advantage of analyzing the industrial alloys – compared to, say, metal ore – is that manufactured alloys display great homogeneity (uniformity of chemical composition and atomic structure). However, XRF, being unable to see carbon, has only a limited (though important) use in carbon steel testing.
